Five Success Tips when using the Voice Prompt

1. * shifts down to the next menu option

2. # returns to the main menu

3. 9 functions as the ENTER key in many cases to confirm an option

4. All entered digit sequences have known lengths - 2 digits for menu option and 12 digits for IP address. For IP address, add 0 before the digits if the digits are less than 3 (i.e. - 192.168.0.26 should be key in like 192168000026. No decimal is needed).

5. Key entry can not be deleted but the phone may prompt error once it is detected PLACING A PHONE CALL PHONE OR EXTENSION NUMBERS

1. Dial the number directly and wait for 4 seconds (Default No Key Entry Timeout); or 2. Dial the number directly and press # (Use # as dial key must be configured in web configuration).

Examples: 1. Dial an extension directly on the same proxy, (e.g. 1008), and then press the # or wait for 4 seconds. 2. Dial an outside number (e.g. (626) 666-7890), first enter the prefix number (usually 1+ or international

code) followed by the phone number. Press # or wait for 4 seconds. Check with your VoIP service provider for further details on prefix numbers.

DIRECT IP CALLS

Direct IP calling allows two parties, that is, a FXS Port with an analog phone and another VoIP Device, to talk to each other in an ad hoc fashion without a SIP proxy.


Elements necessary to completing a Direct IP Call: 1. Both HT502 and other VoIP Device, have public IP addresses, or 2. Both HT502 and other VoIP Device are on the same LAN using private IP addresses, or 3. Both HT502 and other VoIP Device can be connected through a router using public or private IP

addresses (with necessary port forwarding or DMZ). To make a direct IP call

1. Pick up the analog phone then access the voice menu prompt by dial *** 2. Dial 47 to access the direct IP call menu 3. Enter a 12-digit target IP address after the dial tone and voice prompt Direct IP Calling

Destination ports can be specified by using *4 (encoding for :) followed by the port number. Examples:

a) If the target IP address is 192.168.0.160, enter the 12 digit IP address (e.g. 1921680160) after the voice prompt followed by the # key or wait for 4 seconds. The default destination port 5060 is used if no port is specified.

b) If the target IP address/port is 192.168.1.20:5062, enter the 12 digit IP address + *45062 (e.g.

1921680160*45062) after the voice prompt followed by the # key or wait for 4 seconds. NOTE: When completing direct IP call, the Use Random Port should set to NO. You can not make direct IP calls between FXS1 to FXS2 since they are using same IP. CALL HOLD

Place a call on hold by pressing the flash button on the analog phone (if the phone has that button). Press the flash button again to release the previously held Caller and resume conversation. If no flash button is available, use hook flash (toggle on-off hook quickly). You may drop a call using hook flash. CALL WAITING

Call waiting tone (3 short beeps) indicates an incoming call, if the call waiting feature is enabled. Toggle between incoming call and current call by pressing the flash button. First call is placed on hold. Press the flash button to toggle between two active calls. CALL TRANSFER

Blind Transfer Assume that call Caller A and B are in conversation. A wants to Blind Transfer B to C:

1. Caller A presses FLASH on the analog phone to hear the dial tone. 2. Caller A dials *87 then dials caller Cs number, and then # (or wait for 4 seconds) 3. Caller A can hang up.

NOTE: Enable Call Feature must be set to Yes in web configuration page.


Caller A can place a call on hold and wait for one of three situations:

1. A quick confirmation tone (similar to call waiting tone) followed by a dial tone. This indicates the transfer is successful (transferee has received a 200 OK from transfer target). At this point, Caller A can either hang up or make another call.

2. A quick busy tone followed by a restored call (on supported platforms only). This means the transferee has received a 4xx response for the INVITE and we will try to recover the call. The busy tone is just to indicate to the transferor that the transfer has failed.

3. Continuous busy tone. The phone has timed out. Note: continuous busy tone does not indicate the transfer has been successful, nor does it indicate the transfer has failed. It often means there was a failure to receive second NOTIFY check firmware for most recent release.

Attended Transfer Assume that Caller A and B are in conversation. Caller A wants to Attend Transfer B to C:

1. Caller A presses FLASH on the analog phone for dial tone.

2. Caller A then dials Caller Cs number followed by # (or wait for 4 seconds).

3. If Caller C answers the call, Caller A and Caller C are in conversation. Then A can hang up to complete transfer.

4. If Caller C does not answer the call, Caller A can press flash to resume call with Caller B. NOTE: When Attended Transfer fails and A hangs up, the GXW will ring back user A to remind A that B is still on the call. A can pick up the phone to resume conversation with B. 3-WAY CONFERENCING

Bellcore Style 3-way Conference The HT502 supports Bellcore Style 3-way Conference only. Directions for using 3-Way Conferencing:

1. Caller A presses flash to receive a dial tone. (Hook Flash for older model phones). 2. Caller A dials Caller Cs number then # (or wait for 4 seconds). 3. If Caller C answers call, then Caller A presses flash to bring Parties B & C into conference. 4. If Caller C does not answer the call, Caller A can press flash to resume call with Caller B.


CALL FEATURES The HT502 supports all the traditional and advanced telephony features. TABLE 6: HT502 CALL FEATURE DEFINITIONS Key Call Features *30 Block Caller ID (for all subsequent calls) *31 Send Caller ID (for all subsequent calls) *50 Disable Call Waiting (for all subsequent calls) *51 Enable Call Waiting (for all subsequent calls) *67 Block Caller ID (per call) *70 Disable Call Waiting (per call) *71 Enable Call Waiting (per call) *72 Unconditional Call Forward. Dial *72, wait for dial tone. Dial the forward number and

# for a dial tone, then hang up. *73 Cancel Unconditional Call Forward. To cancel Unconditional Call Forward, dial

*73, wait for dial tone, then hang up. *82 Send Caller ID (per call) *87 Blind Transfer *90 Busy Call Forward. Dial *90 , wait for dial tone. Then dial the forward number and #

for a dial tone, then hang up. *91 Cancel Busy Call Forward. To cancel Busy Call Forward, dial *91, wait for dial tone,

then hang up. *92 Delayed Call Forward. Dial *92, wait for dial tone. Then dial the forward number and

# for a dial tone, then hang up.

*93 Cancel Delayed Call Forward. To cancel Delayed Call Forward, dial *93, wait for dial tone, then hang up.

Flash/Hook Toggles between active call and incoming call (call waiting tone). If not in conversation, flash/hook will switch to a new channel for a new call.

T.38 FAX HT502 supports fax in two modes: 1) T.38 (Fax over IP) and 2) fax pass through. T.38 is the preferred method because it is more reliable and works well in most network conditions. If the service provider supports T.38, please use this method by selecting T.38 as fax mode (default). If the service provider does not support T.38, pass-through mode may be used. To send or receive faxes in fax pass through mode, users must select all the Preferred Codecs to be PCMU/PCMA (G.711-u/a).

Keep-alive interval This parameter specifies how often the HT502 sends a blank UDP packet to the SIP server in order to keep the hole on the NAT open. Default is 20 seconds. Minimum value is 20 seconds.

Firmware Upgrade and Provisioning

Enables HT502 to download firmware or configuration file through either the TFTP or HTTP server.

Via TFTP Server This is the IP address of the configured TFTP server. If selected and it is non-zero or not blank, the HT502 retrieves the new configuration file or new code image from the specified TFTP server at boot time. After 5 attempts, the system will timeout and will start the boot process using the existing code image in the Flash memory. If a TFTP server is configured and a new code image is retrieved, the new downloaded image is saved into the Flash memory. Note: Please do NOT interrupt the TFTP upgrade process (especially the power supply) as this will damage the device. Depending on the network environment this process can take up to 15 or 20 minutes.

Via HTTP Server The URL for the HTTP server used for firmware upgrade and configuration via HTTP. For example, ttp://provisioning.mycompany.com:6688/Grandstream/1.0.0.36 :6688 is the specific TCP port where the HTTP server is listening; it can be omitted if using default port 80. Note: If Auto Upgrade is set to No, HT502 will only do HTTP download once at boot up.

Firmware Server Path IP address or domain name of firmware server.

Config Server Path IP address or domain name of configuration server.

Syslog Level Select the HT502 to report the log level. Default is NONE. The level is one of DEBUG, INFO, WARNING or ERROR. Syslog messages are sent based on the following events:

1. product model/version on boot up (INFO level) 2. NAT related info (INFO level) 3. sent or received SIP message (DEBUG level) 4. SIP message summary (INFO level) 5. inbound and outbound calls (INFO level) 6. registration status change (INFO level) 7. negotiated codec (INFO level) 8. Ethernet link up (INFO level) 9. SLIC chip exception (WARNING and ERROR levels) 10. memory exception (ERROR level)

The Syslog uses USER facility. In addition to standard Syslog payload, it contains the following components: GS_LOG: [device MAC address][error code] error message Example: May 19 02:40:38 192.168.1.14 GS_LOG: [00:0b:82:00:a1:be][000] Ethernet link is up


TABLE 10: HT502 INDIVIDUAL ACCOUNT SETTINGS DEFINITIONS

Profile Active When set to Yes the FXS port is activated. SIP Server SIP Servers IP address or Domain name provided by VoIP service

provider.

Outbound Proxy IP address or Domain name of Outbound Proxy, or Media Gateway, or Session Border Controller. Used by HT502 for firewall or NAT penetration in different network environments. If symmetric NAT is detected, STUN will not work and ONLY outbound proxy can correct the problem.

SIP transport User can select UDP or TCP or TLS. NAT Traversal (STUN) This parameter defines whether the HT502 NAT traversal mechanism is

activated or not. If activated (by choosing Yes) and a STUN server is also specified, then the HT502 performs according to the STUN client specification. Under this mode, the embedded STUN client will detect if and what type of firewall/NAT is being used. If the detected NAT is a Full Cone, Restricted Cone, or a Port-Restricted Cone, the HT502 will use its mapped public IP address and port in all of its SIP and SDP messages. If the NAT Traversal field is set to Yes with no specified STUN server, the HT502 will periodically (every 20 seconds or so) send a blank UDP packet (with no payload data) to the SIP server to keep the hole on the NAT open.

SIP User ID User account information, provided by VoIP service provider (ITSP). Usually in the form of digit similar to phone number or actually a phone number.

Authenticate ID SIP service subscribers Authenticate ID used for authentication. Can be identical to or different from SIP User ID.

Authenticate Password SIP service subscribers account password.

Name SIP service subscribers name for Caller ID display.

Use DNS SRV Default is No. If set to Yes the client will use DNS SRV to look up server.

User ID is Phone Number

If the HT502 has an assigned PSTN telephone number, this field should be set to Yes. Otherwise, set it to No. If Yes is set, a user=phone parameter will be attached to the From header in SIP request.

SIP Registration Controls whether the HT502 needs to send REGISTER messages to the proxy server. The default setting is Yes.

Unregister on Reboot Default is No. If set to Yes, the SIP users registration information will be cleared on reboot.

Outgoing Call w/o Registration

Default is No. If set to Yes, user can place outgoing calls even when not registered (if allowed by ITSP) but is unable to receive incoming calls.

Register Expiration This parameter allows the user to specify the time frequency (in minutes) the HT502 refreshes its registration with the specified registrar. The default interval is 60 minutes (or 1 hour). The maximum interval is 65535 minutes (about 45 days).

Local SIP port Defines the local SIP port the HT502 will listen and transmit. The default value for FXS port 1 is 5060. The default value for FXS port 2 is 5062.

Local RTP port Defines the local RTP-RTCP port pair the HT502 will listen and transmit.


It is the base RTP port for channel 0. When configured, channel 0 uses this port _value for RTP and the port_value+1 for its RTCP; channel 1 uses port_value+2 for RTP and port_value+3 for its RTCP. The default value for FXS port 1 is 5004. The default value for FXS port 2 is 5012.

Use Random Port This parameter forces the random generation of both the local SIP and RTP ports when set to Yes. This is usually necessary when multiple HT502 are behind the same NAT.

Refer to Use Target Contact

Used for call transfer, incase server requires this setting.

DTMF Payload Type Sets the payload type for DTMF using RFC2833. DTMF in-audio Send DTMF as inband (in-audio). DTMF via RFC2833 Send DTMF via RTP (According to RFC 2833).

Enable Call Features Default is Yes. Advanced call features and feature codes functions are supported locally.

Offhook Auto-Dial This parameter allows users to configure a User ID or extension number to be automatically dialed upon off-hook. Only the user part of a SIP address needs is entered here. The HT502 will automatically append the @ and the host portion of the corresponding SIP address.

Proxy-Require SIP Extension to notify SIP server that the unit is behind the NAT/Firewall. Use NAT IP NAT IP address used in SIP/SDP message. Default is blank. Distinctive Ring Tone Custom Ring Tone 1 to 3 with associate Caller ID: when selected, if Caller

ID is configured, then the device will ONLY uses this ring tone when the incoming call is from the Caller ID. System Ring Tone is used for all other calls. When selected but no Caller ID is configured, the selected ring tone will be used for all incoming calls.

Disable Call Waiting Default is No. Disable Call Waiting Tone

Default is No.

Ring Timeout Incoming call will stop ringing when not picked up given a specific period of time.

No Key Entry Timeout Default is 4 seconds. Early Dial Default is No. Use only if proxy supports 484 response. This parameter

controls whether the phone will send an early INVITE each time a key is pressed when a user dials a number. If set to Yes, an INVITE is sent using the dial-number collected thus far; Otherwise, no INVITE is sent until the (Re-)Dial button is pressed or after about 5 seconds have elapsed if the user forgets to press the Re-Dial button. The Yes option should be used ONLY if there is a SIP proxy configured and the proxy server supports 484 Incomplete Address response. Otherwise, the call will likely be rejected by the proxy (with a 404 Not Found error). This feature is NOT designed to work with and should NOT be enabled for direct IP-to-IP calling.

Dial Plan Prefix Sets the prefix added to each dialed number.


Use # as Dial Key Allows users to configure the # key as the Send (or Dial) key. If set to Yes, # will send the number. In this case, this key is essentially equivalent to the (Re)Dial key. If set to No, this # key can be included as part of number.

Configure ring or tone frequencies according to preference. By default tones are set to North American frequencies. Frequencies should be configured with known values to avoid uncomfortable high pitch sounds.

SAVING THE CONFIGURATION CHANGES Click the Update button in the Configuration page to save the changes to the HT502 configuration. The following screen confirms that the changes are saved. Reboot or power cycle the HT502 to enable the changes.

FIGURE 5: SCREENSHOT OF SAVE CONFIGURATION PAGE

REBOOTING THE HT502 FROM REMOTE

The HT502 can be remotely reboot by clicking the Reboot button at the bottom of the configuration page. When finished, re-login to the HT502 after waiting about 30 seconds.



SOFTWARE CONFIGURATION Software upgrades are completed via TFTP or HTTP. The corresponding configuration settings are in the ADVANCED SETTINGS configuration page. FIRMWARE UPGRADE THROUGH TFTP/HTTP Our latest official release can be downloaded from: http://www.grandstream.com/y-firmware.htm. To upgrade your unit firmware, follow these steps:

1. Under Advanced Settings webpage, enter your TFTP or HTTP Server IP address (or FQDN) next to the Firmware Upgrade: Upgrade Server field.

2. Select via TFTP or HTTP accordingly.

3. If you plan to use Automatic Upgrade, set it to Yes, otherwise No (this will make it check for upgrade every time you reboot).

IVR METHOD

Firmware server in IP address format can be configured via IVR. If firmware server is in FQDN format, it must be set via web configuration interface. UPGRADE THROUGH HTTP

To upgrade firmware via HTTP, the field Firmware Upgrade and Provisioning: Upgrade Via needs to be set to HTTP. The Firmware Server Path should be set to where the firmware files are located. For example, the user can use the following URL in the Firmware Server Path:firmware.mycompany.com: 6688/Grandstream/1.0.0.29 where firmware.mycompany.com is the FQDN of the HTTP server. It can also be in IP address format. :6688 is the TCP port the HTTP server listening to, default http server listens to port 80. /Grandstream/1.0.0.29 is the RELATIVE directory to the root dir on HTTP web server. UPGRADE THROUGH TFTP

To upgrade firmware via TFTP, set the field Firmware Upgrade and Provisioning: Upgrade Via to TFTP. The TFTP server can be configured in either IP address format or FQDN. To configure the TFTP server via the Web configuration interface, follow these five steps:

1. Open your browser to input the IP address of the HT502 . 2. Enter the admin password to enter the configuration screen. 3. Enter the TFTP server address or URL in the Firmware Server Path field near the bottom of the

configuration screen. 4. Once the Firmware Server Path is set, update the change by clicking the Update button. 5. Reboot or power cycle the unit.

If the configured updating server is found and a new code image is available, the HT502 will retrieve the new image files by downloading them into the HT502 s SRAM. During this stage, the HT502 s LED will blink until the checking/downloading process is completed. Upon verification of checksum, the new code image will be saved into the Flash. If TFTP fails for any reason (e.g., TFTP server is not responding, there are no code image files available for upgrade, or checksum test fails, etc), the HT502 will stop the TFTP process and simply boot using the existing code image in the flash. A firmware upgrade may take as long as 20 minutes over the Internet, or 20+ seconds if performed on a LAN. Grandstream recommends conducting firmware upgrades in a controlled LAN environment if possible.

http://www.grandstream.com/y-firmware.htm


NO LOCAL TFTP SERVER

For users who do not have a local TFTP server, Grandstream provides a NAT-friendly TFTP server on the public Internet for users to download the latest firmware upgrade automatically. Please check the Services section of Grandstreams Web site to obtain this TFTP server IP address. Alternatively, user can download and install a free TFTP or HTTP server in his LAN for a firmware upgrade. A free Windows version TFTP server can be downloaded from: http://support.solarwinds.net/updates/New-customerFree.cfm. TFTP Server Downloading Directions:

1. Unzip the file and put all of the files under the root directory of the TFTP server. 2. Put the PC running the TFTP server and the HT502 in the same LAN segment. 3. Go to File -> Configure -> Security to change the TFTP server's default setting from "Receive

Only" to "Transmit Only" for the firmware upgrade. 4. Start the TFTP server, in the phones web configuration page. 5. Configure the Firmware Server Path with the IP address of the PC. 6. Update the change and reboot the unit.

You can also download the free HTTP server from http://httpd.apache.org or use Microsoft IIS web.

FIRMWARE AND CONFIGURATION FILE PREFIX AND POSTFIX

Firmware Prefix and Postfix allows the device to download the firmware name with the matching Prefix and Postfix. This makes it possible to store ALL firmware with different versions in a single directory. Similarly, Config File Prefix and Postfix allows the device to download the configuration file with the matching Prefix and Postfix, allowing multiple configuration files for the same device to be stored in one directory. In addition, when the field Check New Firmware only when F/W pre/suffix changes is set to Yes, the device will only issue a firmware upgrade request if there are changes in the firmware Prefix or Postfix. MANAGING FIRMWARE AND CONFIGURATION FILE DOWNLOAD

When Automatic Upgrade is set to Yes, Service Provider can use P193 (Auto Check Interval, in minutes, default and minimum is 60 minutes) to have the devices periodically check with either Firmware Server or Config Server, whenever they are defined. This allows the device periodically check if there are any new changes need to be taken on a scheduled time. By defining different intervals in P193 for different devices, Server Provider can spread the Firmware or Configuration File download in minutes to reduce the Firmware or Provisioning Server load at any given time.

FQDN Fully Qualified Domain Name. A FQDN consists of a host and domain name, including top-level domain. For example, www.grandstream.com is a fully qualified domain name. www is the host, Grandstream is the second-level domain, and and.com is the top level domain. FXS Foreign eXchange Office. An FXS device can be an analog phone, answering machine, fax, or anything that handles a call from the telephone company like AT&T. They should also operate the same way when connected to an FXS interface.

An FXS interface will accept calls from FXS or PSTN interfaces. All countries and regions have their own standards.

FXS is complimentary to FXS (and the PSTN). FXS Foreign eXchange Station. An FXS device has hardware to generate the ring signal to the FXS extension (usually an analog phone).

An FXS device will allow any FXS device to operate as if it were connected to the phone company. This makes your PBX the POTS+PSTN for the phone.

The FXS Interface connects to FXS devices (by an FXS interface, of course). DHCP The Dynamic Host Configuration Protocol (DHCP) is an Internet protocol for automating the configuration of computers that use TCP/IP. DHCP can be used to automatically assign IP addresses, to deliver TCP/IP stack configuration parameters such as the subnet mask and default router, and to provide other configuration information such as the addresses for printer, time and news servers. ECHO CANCELLATION Echo Cancellation is used in telephony to describe the process of removing echo from a voice communication in order to improve voice quality on a telephone call. In addition to improving quality, this process improves bandwidth savings achieved through silence suppression by preventing echo from traveling across a network. There are two types of echo of relevance in telephony: acoustic echo and hybrid echo. Speech compression techniques and digital processing delay often contribute to echo generation in telephone networks. H.323 A suite of standards for multimedia conferences on traditional packet-switched networks. HTTP Hyper Text Transfer Protocol; the World Wide Web protocol that performs the request and retrieve functions of a server IP Internet Protocol. A packet-based protocol for delivering data across networks. IP-PBX IP-based Private Branch Exchange IP Telephony (Internet Protocol telephony, also known as Voice over IP Telephony) A general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). The basic steps involved in originating an IP Telephony call are conversion of the analog voice signal to digital format and compression/translation of the signal into Internet protocol (IP) packets for transmission over the Internet or other packet-switched networks; the process is reversed at the receiving end. The terms IP Telephony and Internet Telephony are often used to mean the same; however, they are not 100 per cent interchangeable, since Internet is only a subcase of packet-switched networks. For users who have free or fixed-price Internet access, IP Telephony software essentially provides free telephone calls anywhere in the world. However, the challenge of IP Telephony is maintaining the quality of service expected by subscribers. Session border controllers resolve this issue by providing quality assurance comparable to legacy telephone systems. IVR IVR is a software application that accepts a combination of voice telephone input and touch-tone keypad selection and provides appropriate responses in the form of voice, fax, callback, e-mail and perhaps other media.

MTU A Maximum Transmission Unit (MTU) is the largest size packet or frame, specified in octets (eight-bit bytes), that can be sent in a packet- or frame-based network such as the Internet. The maximum for Ethernet is 1500 byte. NAT Network Address Translation NTP Network Time Protocol, a protocol to exchange and synchronize time over networks The port used is UDP 123 Grandstream products using NTP to get time from Internet OBP/SBC Outbound Proxy or another name Session Border Controller. A device used in VoIP networks. OBP/SBCs are put into the signaling and media path between calling and called Caller. The OBP/SBC acts as if it was the called VoIP phone and places a second call to the called Caller. The effect of this behavior is that not only the signaling traffic, but also the media traffic (voice, video etc) crosses the OBP/SBC. Without an OBP/SBC, the media traffic travels directly between the VoIP phones. Private OBP/SBCs are used along with firewalls to enable VoIP calls to and from a protected enterprise network. Public VoIP service providers use OBP/SBCs to allow the use of VoIP protocols from private networks with internet connections using NAT. PPPoE Point-to-Point Protocol over Ethernet is a network protocol for encapsulating PPP frames in Ethernet frames. It is used mainly with cable modem and DSL services. PSTN Public Switched Telephone Network. The phone service we use for every ordinary phone call, or called POT (Plain Old Telephone), or circuit switched network. RTCP Real-time Transport Control Protocol, defined in RFC 3550, a sister protocol of the Real-time Transport Protocol (RTP), It partners RTP in the delivery and packaging of multimedia data, but does not transport any data itself. It is used periodically to transmit control packets to participants in a streaming multimedia session. The primary function of RTCP is to provide feedback on the quality of service being provided by RTP. RTP Real-time Transport Protocol defines a standardized packet format for delivering audio and video over the Internet. It was developed by the Audio-Video Transport Working Group of the IETF and first published in 1996 as RFC 1889 SDP Session Description Protocol is a format for describing streaming media initialization parameters. It has been published by the IETF as RFC 2327. SIP Session Initiation Protocol, An IP telephony signaling protocol developed by the IETF (RFC3261). SIP is a text-based protocol suitable for integrated voice-data applications. SIP is designed for voice transmission and uses fewer resources and is considerably less complex than H.323. All Grandstream products are SIP based STUN Simple Traversal of UDP over NATs is a network protocol allowing clients behind NAT (or multiple NATs) to find out its public address, the type of NAT it is behind and the internet side port associated by the NAT with a particular local port. This information is used to set up UDP communication between two hosts that are both behind NAT routers. The protocol is defined in RFC 3489. STUN will usually work well with non-symmetric NAT routers. TCP Transmission Control Protocol is one of the core protocols of the Internet protocol suite. Using TCP, applications on networked hosts can create connections to one another, over which they can exchange data or packets. The protocol guarantees reliable and in-order delivery of sender to receiver data.

UDP User Datagram Protocol (UDP) is one of the core protocols of the Internet protocol suite. Using UDP, programs on networked computers can send short messages known as datagrams to one another. UDP does not provide the reliability and ordering guarantees that TCP does; datagrams may arrive out of order or go missing without notice. However, as a result, UDP is faster and more efficient for many lightweight or time-sensitive purposes. VAD Voice Activity Detection or Voice Activity Detector is an algorithm used in speech processing wherein, the presence or absence of human speech is detected from the audio samples. VLAN A virtual LAN, known as a VLAN, is a logically-independent network. Several VLANs can co-exist on a single physical switch. It is usually refer to the IEEE 802.1Q tagging protocol. VoIP Voice over the Internet. VoIP encompasses many protocols. All the protocols do some form of signaling of call capabilities and transport of voice data from one point to another. e.g.: SIP, H.323, etc.
